How To Size A Rigid Cock Ring (Dick)


If you have never used a cock ring, or don’t know why someone would, we addressed related questions in our post How Do Cock Rings Work? and I can tell you from experience they are a great accessory for any man (and couple!) to own and use: A Solid Investment.

There are a variety of cock ring types available and a good primer on the basics can be found on the Sex Is Fun website. Buying the right size ring is important, especially if it is a rigid ring made of something like steel or aluminum. I have acquired a modest collection of these in recent years (sample few) and would like to share some sizing tips with you. This is a solid guideline but not a guarantee. I recommend you start out with a ring on the less expensive side and upgrade to a premium ring later, once you are confident you have found your perfect size and are looking for a ring to last a lifetime.

What follows is a suggested technique to determine the appropriate size for a rigid or semi-rigid cock ring which fits on the base of your cock behind your balls. Complete the steps, input your result, and then calculate. I’ll make some product suggestions for you once you have finished your calculation. Find an assistant to give you a hand… not only is it helpful but it makes the whole exercise a lot more fun!

Tie A Yellow Ribbon

Tie A Yellow Ribbon Around It
It doesn’t have to be yellow… but once you get the song out of your head find a ribbon with some width to it, like a half inch wide (string works but is not ideal). Wrap it around the base of your dick, behind your balls, cross over in front, and pull the ends with gentle force. It’s tight enough when you see a little skin begin gather (like pleats) beneath the ribbon. It may not feel tight enough, just stay with me.

Not Too Tight!

Not Too Tight!
Tight may be good for vaginas but we’re talking about the future well being of your most treasured friend here. Get over ambitious with pulling on those ribbon ends and you could end up showing off your new cock ring in the Emergency Room. You want a little skin gathered beneath the ribbon, but not too much!

Mark It

Mark It
Use a pen to draw a straight line across the overlapped ribbon. It really helps to have an assistant with this, just be careful you don’t end up with a smiley face somewhere unexpected.

Measure It

Measure It
Straighten the ribbon and measure between your two lines in inches (or cm and convert to inches). Convert fractional portion (i.e. 1/8) into a decimal (i.e. 0.125) to use the calculator below.

Calculate It
Desired Fit
Enter your dick circumference as a decimal value in inches (i.e. 7¼ would be 7.25), select your desired fit (if you are buying your first ring go with “Basic”) and then click Calculate.

Husband Tentative About Pegging


Hi guys, love your site and I need some advice.

I have a hot fantasy that I want to do with my husband and I know he does too, but he is afraid or has hesitation. I have wanted to put on a strap-on, bend him over and give him anal for so long now. He knows that I want this too and every so often he will send me a message hinting that he might be into it. Like when he sends sexy pictures of couples together from your site and included are some of the ones with couples doing this.

Hitachi Magic Wand Hack

TIP: Magic Trick – Hack the Wand (Dick)


The Original Magic Wand

It’s hard to imagine anyone reading this who doesn’t already know about, or own, the [formerly Hitachi branded] Original Magic Wand. They have been available commercially in mainstream markets since 1968 and are seemingly ubiquitous in porn. I have labeled ours a Powerful Orgasm Extractor because it does the trick for Jane every single time and quickly too! Of course, it’s a bit powerful and can overwhelm the senses… which is why I hacked the power supply to create More >


Our Recommendations, Updated!


We occasionally take a day or two off from our regular routines to spend them focused on each other (you can read about some of those days here) which involve cracking open the sex toy vault to liberate our favorite forms of entertainment. It occurrs to us that we really have a significant collection of stuff… some of which we have written about (or reviewed) but much of which we have never mentioned here.

There is so much crap on the market! We think we have sorted through enough lousy More >

Revel Body SOL

Revel Body SOL – Sonic Vibrator (Improved)


hover to see other side

SOL is the latest incarnation of the much loved original Revel Body Sonic Vibrator and it offers up some significant improvements over a vibe Jane had previously dubbed one of the best she had used. This new version looks nearly identical, is it really any better? We tried it out side by side with the original Revel Body ONE and the answer is YES!

What We Really Liked • More powerful than the original • Simplified frequency selection • Better design of Core Tip More >

Sexual Preference, Porn, and Secrets


Hi. I have some issues that I hope someone can help me with. First of all, I live in a very small town with very few counseling resources. Plus everyone knows everyone’s business so am hesitant to ask for local help. Came across this website (thru and thought maybe this could be a safe place for me to ask some stuff. I wrote an extensive (and I do mean extensive) email, but it was too long to send. In a nutshell, some of my issues include a strained marriage due to a More >

20th Anniversary

20 Years And A Thank You! (Dick)


Jane and I celebrated 20 years of marriage yesterday. Holy crap! Has it really been that long since Jane teased me in the car? We had a great day together 20 years ago and another one just yesterday. I am sharing this with you because we have this site and its readers to thank for making our 20th special. I’ll get back to that further down, but let me first tell you about our day!

Unlike our wedding day so long ago, this day started with sex. Showers first, then back to bed… I can’t think of a More >


Advanced Cock Ring (Tantus)


Tantus Advanced Cock Rings

A silicone cock ring which has flex (like it’s easily squeezed into an oval shape) but very little stretch. It is made to be worn behind the balls and provides excellent retention for erectile tissue. “Advanced” refers to the size (Tantus’ smallest of this type) combined with this ring’s lack of stretch.

What We Really Liked

• Comfortable to wear • Harder, thicker erection • Delayed ejaculation • Durable and easy to clean

The Pleasures Of Giving Oral Sex (Dick)


Receiving oral sex is great for many reasons which need no explanation, but what about giving oral sex? Can a person find pleasure in performing an act which, on the surface, appears to be so one sided? Yes, of course. But perhaps it is not entirely for the altruistic reasons you suspect. Let me back up to get a running start at this.

You’ve Got A Lot Of Nerve

Have You Checked In Lately? (Dick)


People change. They grow, they contemplate, they fantasize. Sometimes they get bored… and every once in awhile there may be a paradigm shift that spins a person’s perspective, ideals, and desires in unexpected directions.

If you are in a long term relationship and you think you have your finger on the pulse of your partner’s desires you might want to double check your assumptions. Maybe you don’t know the whole story any longer.

Or perhaps it is you who has discovered something new about what More >
